Specication of Letters Patent.

Application led March 23, 1916. Serial No. 86,085.

To all whom t may concern Be it known that I, RUDOLPHHOFFMAN, a

citizen ofthe United States, residing at- Kankakee, in the county of Kankakee and stoves of the so-called wickless type.` In

such stoves each burner comprises a relativelyshallow bow-l or trough contalnlng a quantity of oil. Theltrough 1s supphed with oil from a well or receptacle in which well to the troughs.

the oil is maintained at a certain level. "If, therefore, the level of oil in the trough 1s to be at the right height, the trough must be vproperly located with reference to the well.

Usually two or more troughs located side by side are supplied `from a single well by means of a feed vpipe extendingffrom the It will be evident that l'if the stove is placed upon a floor which is not horizontal, the oil will stand at different levels in the several troughs.

The object of this invention is to provide convenient, self-locking means for adjusting the troughs into horizontal position and thus compensate for any lack of'horizontality of the door. or other surface on which the stove is set.

In the accompanying drawings, Figure l is a fragmental front elevation of a wickless oil stove embodying the features of my invention. Fig. -2 is a vertical sectional view of 4the adjusting means, taken in the plane of dotted line 2-2 of Fig. 3. Fig. 3 1s a view taken from the right-hand side of Fig. 2.

While the invention may be embodied in stoves of any preferred construction, I have herein shown a stove having three burners A of the wickless blue-iiame oil-fuel type. Each burner comprises a bowl or trough 1 similar to the onev shown in vPatent No.` 1,154,637, dated September 28, 1915. The troughs are supported upon and communicate with a feed pipe 2 which is connected at one 4end with a well or oil receptacle 3. Upon the well 3 is a font or reservoir 4 the outlet to which isA sealed or unsealed by the rise or fall of the oil-level in the well 3. Adjacent to the well 3 the feed pipe, passes freely through, and is supported within, an opening in the wall or framework ofl the stove. The end -of the feed pipe opposite to' the well is closed and is supported for vertical adjustment. The end wall 5 has a vertically elongated` opening' 6 through which the feed pipe extends freely.

7 1s a plate having a circular opening 8 1n which the feed pipe is supported. The plate 7 is secured to the end wall 5l by means of a bolt 9 extending through the end wall and through a slot 10in the plate 7. 11 is a nut on the bolt. rllhe slot 10 is curved upon the arc of a circle which is eccentric to the opemng 8. 12 is a handle `on the plate 7. It will be seen that as the plate 7 is turned the adjacent end of the feed pipe will be raised or lowered.

If after the stove has been set in the des1re d nl ace, it is found that the oil level varies 1n the troughs 1, the nut 11 is loosened, the plate 7 is turned to raise or lower the adjacent end of the feed pipe until the oil stands at the same level in al1 the trpughs, and the nut again tightened. It will be evident that the weight of the feed pipe and the several burners is supported by the top wall of the slot l0 resting vupon the bolt 9. As this wall approximates a horizontal surface, it will be seen that considerable resistance is oered to downward movement of the feed pipe, so that even if the nut 11 were left loose, there is security against accidental dropping of the burners.

I claim as my invention:

1. A stove having, in combination, a staing member having a c1rcular opemng through which the feed-pipe extends, said member having a slot, different portions of the slot being at different distances from the opening in said member, a supporting member on the end Wall and extending through the slot, and a handle portion on the first mentioned member.

2. A stove having, in combination, a feedc pipe, a burner supported upon the feed-pipe, a member having an opening in which the feed-pipe is supported, said member having a curved slot above the opening, diierent portions of said slot being at different distances from said opening, anda supporting 10 member passing through said slot.

In testimony whereof, I have hereunto set my hand. l

RUDOLPH HOFFMAN.
